Instance Attribute Details

#data ⇒ String

The data blob to put into the record, which is base64-encoded when the
blob is serialized. When the data blob (the payload before
base64-encoding) is added to the partition key size, the total size must
not exceed the maximum record size (1 MB).

Returns:

(String)
—

The data blob to put into the record, which is base64-encoded when the blob is serialized.

#explicit_hash_key ⇒ String

The hash value used to determine explicitly the shard that the data
record is assigned to by overriding the partition key hash.

Returns:

(String)
—

The hash value used to determine explicitly the shard that the data record is assigned to by overriding the partition key hash.

#partition_key ⇒ String

Determines which shard in the stream the data record is assigned to.
Partition keys are Unicode strings with a maximum length limit of 256
characters for each key. Amazon Kinesis Data Streams uses the partition
key as input to a hash function that maps the partition key and
associated data to a specific shard. Specifically, an MD5 hash function
is used to map partition keys to 128-bit integer values and to map
associated data records to shards. As a result of this hashing
mechanism, all data records with the same partition key map to the same
shard within the stream.
